Can't boot into windows after resizing partitions

understood ....

do you need me to output any info ?

btw i reformatted the partition as FAT since I don't think I'll be needing the capabilities of extFAT.

I also googled this and found this thread .... would fixing the hybrid MBR according to the first post in this thread be the solution ?

Repairing Boot Camp after creating new partition

That thread has multiple problems rolled into one. I would not use it, especially the text marked as a solution (which came from http://nerdr.com/bootcamp-partition-lost-repairing-mac-partitions/ ) It is only appropriate for a specific problem. It causes data loss in many other situations.

The two links I provided should be the ones used. They are appropriate for your 5 GPT entry problem.

ok.

sorry, would you please post the 2 links i should follow one more time ? I am browsing thru the pages of this thread and i'm not sure which ones you mean ....

Just one - Re: [Help] Can't boot to windows (8.1) after resizing partition .

i read the instructions, my situation is a bit different so this is what I did, I have not yet typed "w" to write the changes. please inform if made a mistake ?

i do have another question: the original hybrid MBR layout included AB (recovery partition) - is it necessary to be present in the hybrid MBR ? i skipped it because I think that MBR's can only handle up to 4 entries (including the EFI).

so far both OS's show the FAT32 SHARE partition i created.

Thanks again Loner T for everything, this was an epic journey (at least for a novice like me) ....

to do this i had to disable sip ... is it safe to enable it now that i have everything else squared away ?

Since you chose 2 4 5 instead of 3 4 5, please go to Windows Disk Management (do not modify anything) and post a screen shot. The Recovery HD looks like Free Space to Windows, which is why I use 3 4 5. This allows 2+3 to look like one contiguous set, even though GPT sees them as separate partitions.

the unallocated space shown in disk management is 620 MiB (650 MB, i.e. the reported size of the Recovery HD partition). it is graphically positioned with the HFS+ partition to the left of it and the NTFS partition to the right of it.

I would prefer to leave it this way .... Reason being that I may need to view files on the HFS+ partition while in Windows. Whereas I would not need to that with the Recovery HD partition. is there another reason to keep it in the MBR ? I assume I can still boot into recovery if I need to ?

My windows partition (in Control Panel/devices) is identified as an MBR partition.

regarding SIP, should I re-enable after i'm finalized with everything ?

As long as you never use Windows LDM to manipulate the "unallocated" space, you should be fine. You can re-enable SIP. Please be aware that you have a non-standard layout, and each Software Update from Apple can potentially cause data corruption, so make very good backups on a daily basis.

question: why does it matter if the Recovery HD partition is not on the MBR, since it's a GPT ?

so there is a good reason to maintain the recovery HD partition, meaning that as new software updates get pushed to my mac (and possibly to the recovery HD partition), if I keep partitions 3 4 5 in the MBR then I should not have a data corruption issue with future apple software updates ?

if this is actually the case, then I will go back and change the MBR. but then I will then no longer see the Macintosh HD partition in windows, i suppose I can work around file sharing between OS's by copying them to the share or NAS when in os 10.

I suggest building an OS X installation on an external disk, which ensures that the Mac can be booted and run regular Software Updates on this OS X-only disk.

The current "unallocated" space is prone to possible corruption.

that's not practical for me.

so should I go back to gdisk and write the MBR with GPT partitions 3 4 5 rather than keep it as 2 4 5 ?

like i said, access to the HFS+ file system from within windows is something I can live without.
